The singer jetted off to South Africa this weekend for Sport Relief and made an appeal for malaria aid. She tweeted a picture when she got there, writing: Greetings from SA.. 😘😘😘😘

The 'Fight For This Love' hitmaker herself contracted malaria a year after climbing Mount Kilimanjaro for charity.

In a video message, she spoke about her own terrifying experience and appealed for help to fight the disease: "When I climbed Kilimanjaro for Comic Relief five years ago it was honestly one of the hardest things I've ever done.

"The motivation lay in knowing it could help in eradicating malaria and ultimately saving lives by providing mosquito nets.

"I didn't for one minute think that only a year later, I would get malaria myself and become so ill that, at one point, I was given 24 hours to live.

"It was the scariest thing you could ever imagine for me and for my friends and family. The pain I felt and went through, it's what so many people go through, all because they don't have a mosquito net which could save their life.

"I was lucky, I had the best care I could get. Some people are not so lucky. A £5 mosquito net could keep a child safe and really does help."

But she looked like she also found some time to let her hair down, and posted a picture of herself enjoying some downtime with mates.

"All you need are great friends and a beat 😜 #memories 👯👯👯," she said.

We're presuming this was the night before that early-morning selfie. Loving the animal-print top btw.
